LOG-BOOM SECURING DEVICE Application filed January 21, 1930. Serial: No. 422,277.

This inventionrelates to improvements in means for securing the side sticks utilized for log booming-in rigid relationship, one to, the other, with particular illustrative reference herein had to the engaged assemblyof right angularly disposed end boom sticks in a manner whereby slippage of the same is overcome.

Numerous so-called improvements have been devised to the end of eliminating center bores and such, mainly being. drawn to chain structures encircling the extremities of asso ciated logs in a manner whereby friction is utilized in preventing chain slide. Exces- 5 sive equipment cost and complicated assem- .bling prohibits commercial use of the same to any large extent.

For this reason, such have largely been discarded in favor of the old expedient of using a chain having a ring member secured to one extremity and a toggle bar secured to the opposite extremity, the latter being drawn through the logbores and returned about the log for passage through the ring. A relatively loose connection handicaps the structure, more especially to the corner side sticks, .where a tight abutment of one to the other is especially desirable for transportation in heavy seas.

The present invention overcomes the foregoing objections, having for an object, the

rovision of inexpensive means adaptable to secure retention of a chain securement with accommodations to selective ofplural ad- 5 justments, as will, with further and more specific objects and advantages, become apparent in the following description and claims. v

The invention relates to mechanism includ- 40 ing the former chain toggle bar and ring member, and comprising structure cooperative therewith effective to rigidly engage se lective of interconnected chain links, being of a form adaptable to plural link engage ment, consisting in the novel construction, ar-

rangement and combination. of cooperative parts, as hereinafter described and specificallyv set forth in the claims annexed.

In the drawings, wherein the preferred embodiment of the invention is shown in its application to right angularly disposed end and side boom securing logs,-

Figure 1 illustrates a top plan View of the invention, the bore of one'log being indicated by a section taken therethrough. Fig. 2 is a detail transverse vertical section taken substantially on line 2-2 of Fig. 1; and Fig. 3 is a longitudinal vertical section. online 3--3 of Fig- 1. p

Re'ferencebeing had thereto, numerals 4, m 5, indicate logs havingrespective apertures 6, 7, bored through the same adjacent abutting extremities 8, 9. Arranged to be drawn through said bores, I provide conventional means comprising a chain 10 consisting in a plurality of inter-connected links 11, a ring C member 12 and a toggle bar 13 being secured to the opposite extremitles.

Procedure has been to pass said toggle bar through the ring by pivoting the former about its axis .14 to lie in the longitudinal plane of the chain, the toggle bar being repivoted into transverse disposition whereby the same will, in the reassertion ofv chain stress, contact the inner plane edges to diametrically oppos-ite face portions of the ring.

Practice has also been to wrap the links and toggle bar about the chain portion 10 to engage link peripheral obstructions presented, in attempting to provide tension by the interlodgment of one to another. Excessive strain, responsive to heavy weather conditions, induces a slackening.

Such mechanism is not new, except as taken With associated hereinafter described novel structure.

Reference being had particularly thereto,

contemplate a locking member 16, which, as indicated.,includes a body 17 providing an ral of the latter being carried therein. Said slot, Fig. 2, is of a width adaptable to prevent associated connecting links transversely disposed from passing through the same.

The'peculiar arrangement is deemed a decided contribution to booming-log securement, in view of a locking member attaining positive retention of selective links of a chain extension, with means including the annulet l8 and link guiding web 21 projecting arcuately Within the orifice to enclose said aperture whereby the member 16 is assured positive retention in a manner to guide and expedite passage of the link therethrough. Said arc, inwardly disposed to the normal concentric wall of the orifice, presents the links such that the same are disposed to be readily slid within the slot.

In operation, chain 10 is passed through respective bores 6, 7, toggle bar 13 being pivoted to pass the same through orifice 19. The chain links are drawn through the orifice by riding the same on web periphery 21 to attain the tension desired, whereat a link is slid within the slot to abut extremity 520 The operation is preferably repeated to provide a pair of links Within such restricted throat 20, the projecting chain portion 10 subsequently being" wrapped about portion 10 or allowed todra its-desired. lVhile I have described the invention in the form now preferred, I do not wish to confine myself specifically thereto, except as limited by the scope of the claims hereto annexed.

What I claim, is,'

1; Securing means for log booms, said means comprising, in combination, logs bored transversely adjacent opposing ends, a chain arranged to'be passed through said bores, a locking member, means to securely retain said member in pivotal engagement to one extremity of said chain, said retaining means including'an annulet of said member having a web disposed peripherally thereabouts, and means integral with said web for detachably engaging respective links of the opposite end of said chain, said last named means including an orifice of a width sufiicient to allow of the free passage of said chain links therethrough, anda constricted throat communicating with said orifice, said throat being of a width less than the transverse periphery of respective links, and'of a length suiiiciently in excess of said transverse periphery as to permit of plural of said links being retained in aligned relationship therein;

2. Securing means for log booms, said means comprising logs bored transversely adjacent opposing ends, a chain arranged to be passed through said bores, a locking member, means to securely retain said member in pivotal engagement to one extremity of said chain, saidretaining means including an annulet of said member having a web disposed peripherally thereabouts, and means integral with said web for detachably engaging respective links of the opposite end of said chain, said last named means including an orifice of a width suflicient to allow of the free passage of said chain links therethrough, and a constricted throat communicating with said orifice, the Width of said throat being confined such as to prevent chain links inserted longitudinally therein being vertically displaced from the same.-

3. In chain securing means for log booms, the combination with a chain comprising a plurality of interconnected links, one end thereof carrying a ring link, of a locking bar having an orifice pierced through the same for pivotably securing said ring link, said bar providing a separate orifice of a configuration accommodating the free passage of the chain links of the oppositional free end therethrough, and a constricted throat communicating with said last named orifice, said throat being of a length suflicient to allow of the reception of plural transversely aligned links therein.

4. In apparatus as defined in claim 3, wherein the'orifice in said bar accommodating the securing of the ring link thereto is disposed in alignment with the longitudinal plane of the throat.

5. The combination with the logs of a log boom, of an approximate rectangularly arranged series of logs for embracing the same, said logs bored transversely through opposite extremities, and means for adj ustably connectingeach of said embracing logs to the next adjacent embracing log, said means comprising link chains arranged to be passed through respective pairs of adjacent log bores, and means supported by one end of each of said chains for securing the oppositional end of the same, said means comprising a locking bar providing an approximate key-hole configured opening for passage and selective retention of the links of the oppositional chain end therethrough, said supporting means for the locking bar comprising an orifice pierced through the same separably from said keyhole opening for pivotal connection of a chain link thereto.

6. In chain securing means for log booms, the combination with a chain comprising a plurality of inter-connected links, of a looking bar, one end of said chain pivotally supporting saidlocking bar, said pivotal support comprising an orifice pierced through said bar for connection with said chain end, said locking bar also providing a separate opening configured to accommodate the free passage of the chain links through a portion of the same, and having a constricted throat communicating with the aforesaid portion of the opening affording reception of a link hav ing its transversal disposed in longitudinal alignment therewith. v a

7. In apparatus as defined in claim 6,

wherein the portion of said opening accommodating the free passage of the chain links therethrough presents a convex Wall projecting inwardly of one side for guiding the links passed therethrough to align selective links for ready insertion to the constricted throat.
